Variables inside AI Agent Tools do not exist (BUG)

[Luar_AS]

Describe the problem/error/question

I’ve been having this issue quite a few times since the latest release (1.83.2 & 1.84.1)

In summary the variables inside AI Agent tools simply do not show up, they wither say “no input data” or this:

Please share your workflow

Th e problem seems to be related to the tool and not workflows but here is a snippet:

Information on your n8n setup

• n8n version: 1.83.2/1.84.1
• Database: Supabase
• **n8n EXECUTIONS_PROCESS setting (default: own, main):**I am not sure where to get that info.
• **Running n8n via (Docker, npm, n8n cloud, desktop app):**Cloud

Hey @Luar_AS

In your pinned data, you dont have a “phone” property in the incoming object so $json.phone would be undefined. Could this be the reason why?

{
  "id": 278,
  "body": "quais são os médicos disponiveis",
  "from": "61455607677",
  "to": "me",
  "sentiment": null,
  "user_id": 11,
  "time": "07:09:45",
  "date (y/m/d)": "2025-03-24",
  "priority": null,
  "keywords": null,
  "file": null,
  "dayOfWeek": "Monday"
}

Yeah I know, the screenshot was taken after I hardcoded that variable through a set node, then I deleted it (cause didn’t work)

I opened a ticket in the support and the issue kinda fixed itself and the n8n guys couldn’t reproduce it, it just worked again on the next day.

Thanks Jim
